Add support to load your favourite SA-MP maps into the MTA-SA!

• https://forum.mtasa.com/topic/130386-rel-sa-mp-map-loader

Even works on this kinds of crazy map

• sampobj - provides the core functionality to load the samp.img, cols & texture materials.
• sampmap - SAMP Maploader, loads the map files either from specific format or SA-MP Texture-Studio file.

1. places the sampobj and sampmap into your mta-resrouces folder
2. in sampmap resources, find a file nammed sampmap.lua , it already contains a example map made by samp texture-studio (special thanks to author Unu Alex for the creation of this hard work.), you can add your own map under this file.
3. start the resources sampobj and sampmap & enjoy, you can check out /maptest command to teleport you to the sample example samp map.

• createSAMPObject(model_id,x,y,z,rx,ry,rz)
  • note the mode_id can be either sa stock object or an id from samp_model.
• setObjectMaterial(object,mat_index,model_id,lib_name,txd_name,color)

• Currently the material color is somehow bugged, especially the one contains the alpha materials.
• Drawdistance issue, due to the engine limitation the max distances viewdistance of a normal object is 300 unit, if your map contains the wide areas of custom samp objects, the far distances objects might not visible.
• High Memory Useage, due to the MTA current don't have the support of server-side defined object ids, therefore inorder to keep the original samp model id works i did a big mapping array to keep the mta-allocated ids & orignal samp ids in relation. however the down-side is the high RAM use, it might needs to takes some further optimzation in the furtue.
• Currently no SetObjectMaterialText Support, i'll do it in the furture, do check up my github :p
